Luhnow: Keuchel will not return in regular season

The left-hander has been sidelined since Aug. 27 with shoulder inflammation, and general manager Jeff Luhnow told reporters Monday that Houston would have to "go pretty deep" into the postseason to get Keuchel back on the mound.

An MRI on Keuchel's shoulder earlier this month revealed no structural damage, but the reigning AL Cy Young winner has yet to resume throwing.

The Astros entered play Monday sitting 9 1/2 games back of the Texas Rangers in the AL West, and three games back of the second wild-card spot.

Keuchel is 9-12 with a 4.55 ERA and 1.29 WHIP across 26 starts. Despite his early-season struggles, the 28-year-old went 3-1 with a 3.10 ERA in August before hitting the DL.
